Abstract:
A spectrophotometric catalog is presented, combining results of
numerous observations by Pulkovo astronomers at different observing
sites. The catalog consists of three parts: the first contains the
data of 602 stars in the spectral range 320-735 nm with a resolution 5
nm; the second one contains 285 stars in the spectral range of
500-1080 nm with resolution10 nm and the third one contains 278 stars
combined from the preceding catalogs in spectral range 320-1080 nm
with resolution 10 nm. The data are presented in the absolute energy
units W/mm, with step of 2.5 nm and with an accuracy no more than 1.5
- 2.0%.
Description:
A complete list of the observed stars is given in Table 4. The
following information about the stars is given: HR and HD numbers, the
Bayer's name, the number of independent scans of the spectrum
(short-/long-wavelength range), equatorial coordinates for 2000.0,
spectral type from the 1982 version of the BS catalog, magnitude V and
color index B-V from the same source. Information on binarity and
variability is given in the remarks following Table 4. For the visual
binaries, the separation and m are taken also from the BS . For the
variables, variability type and magnitudes at the maximum and minimum
light and the period are from the General Catalog of Variable Stars
(Kholopov et al. 1985-1990) and its three Supplements (Inf. Bull. Var.
Stars Nos. 2681, 3058, and 3323). The final energy distribution data
in the range 320-1080 nm with a step 2.5 nm, expressed in W/m2/m (or
10^-6^arg/cm^2^/s/nm in cgs) given in Tables 5, 5a and 6. Tables 5
contains the combined data covering the wavelengths 320-1080 nm and
Table 5a is for the stars having data only in the 500-1080 nm range.
All the data are for the same effective spectral broadening, 10 nm.
The data covering only the wavelengths 320-735 nm (with effective
spectral broadening of 5 nm) are presented in Table 6.

Note on table5.dat, table5a.dat, table6.dat:
The flux files contain blocks of data for 7 stars, introduced by
at least 8 blanks and the list of the 7 HR numbers; the lines
which follow are mode of 8 columns containing the wavelength (in nm)
followed by the absolute fluxes (in W/m2/m = 10-6 erg/cm2/s/nm)
of each of the 7 stars.
Note on getsp:
This file is a short script in Unix C-shell which, given a HR
number, lists the spectrophotometry from the flux files.
